Correct Answer: C

Rationale: Encouraging physical activity is an effective non-restraint intervention for managing confused clients. It helps reduce agitation, promotes circulation, and may decrease the need for restraints. Choice A is incorrect as using full-length side rails can potentially restrict a client's movement, which is counterproductive to avoiding restraints. Choice B, while emphasizing monitoring, does not directly address alternatives to restraint use. Choice D is also incorrect as removing clocks from the client's room does not directly address managing confusion and reducing the need for restraints.

Correct Answer: A

Rationale: Choice A is the correct answer because as individuals age, there is a normal decline in cardiac efficiency, leading to a slower return to baseline heart rate after exercise. This statement demonstrates an understanding of an expected change related to aging. Choice B is incorrect as vision typically declines with age due to changes in the eye's structure. Choice C is incorrect because aging usually leads to a decrease in skin elasticity. Choice D is incorrect as hearing tends to decline rather than become more acute with age.

Correct Answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

Correct Answer: A

Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.

Correct Answer: B

Rationale: The goal 'The patient will walk 100 feet using a walker by the time of discharge' is the most appropriate goal for a patient who has had a total hip replacement because it is specific, measurable, achievable, and individualized. This goal sets a clear target for the patient's mobility progress post-surgery. Choice A is too vague and does not provide a specific target distance or method of ambulation. Choice C focuses on the nurse's actions rather than the patient's progress. Choice D lacks specificity in terms of distance or assistance required, making it less measurable and individualized compared to Choice B.
